IMPROVEMENT IN HAY-PRESSES.;

Specification forming part ofLetters Patent No. 3,394, dated December30, 1843.

To all whom it may concern.-

Be it known that I, SAMUEL Hnwir'r, of Allensville, Switzerland county,State of Indiana, have invented a new and useful Improvement in Pressesfor Pressing Light Substances into Bales-such as Cotton, Hay, Ste.-called I-Iewitts Improved Presswhich is described as follows, referencebeing had to the annexed drawings of the same, making part of thisspecification.

My invention and improvement consists in driving into the box thesubstances to be pressed .by machinery operated by manual, horse, orother power simultaneously with the operation of reversing the motion ofthe screw which presses` the substance into abale, instead of tramplingby the attendants, as heretofore. p v

One of the arrangements of machinery that I have used to effect thebefore-mentioned object is described as follows. Various arrangements,however, may be used; but this has proved effective. It' consists of anextension of the two end timbers, A, or posts of the box, united attheir upper ends by a cap, `B, forming a gallows, in which cap twopulleys, o, are inserted, and between said posts a driver, D, fordriving the substance into the box, rises and falls in the manner of amonkey of a piledriving machine, to which is affixed a togglejoint, E,to which a cord, F, or chain is attached, leading over said pulleys anddown to another pulley, G, let into a block fastened to the -lower endof one of the posts, and leading thence to an eye or ring, r, fastenedto a sliding hoop, H, which moves around in a groove in the periphery ofa grooved wheel,.I, and to which eye the cord F is made fast, which`hoop is perforated with an oblong mortise, J,

in which works a hook, K, attached to' the wheel, for locking andunlocking said hoop with the wheel. The wheel is placed in a horizontalposition upon the lever L, attached to the nut Mof the screw N below thebottom beam of the frame. The hook K, for connecting and disconnectingthe hoop and wheel, is

`inserted into a mortise in the wheel, having a vertical axle, a,attached to it, passing through the wheel into the end of a groovedsegment arm or lever, 0,'perforated with a segmentl groove, into whichis inserted a bolt, P, attached to a horizontal trip-lever, Q, whosefulcrum b is inserted into the under side of the wheel I. Thistrip-lever enters a notch in the upper end of a vertical forkedtrip-lever, R, whose fulcrum f is in a casting or box screwed or boltedto the under side of the wheel I. These trip-levers are to be made tostrike against permanent stops S s, inserted into the base or foundationof the frame of the press, in the manner and for the purpose hereinafterdescribed. A spring pole or rod, T, is fastened to one of the posts toprevent the hoop H from turning beyond the point at which Vit isrequired to be arrested. The follower U on the head of thepressing-screw N, the pressing-screw N, the nut lVI, the box WV, anddoors X are made in the usual manner.

The operation is as follows: Ihe follower U being up or raised in thebox, the doors X are closed, made fast, and the driver D is raised. .Iheattendant fills the box W with loose hay or cotton. The horse movesround with the lever Ii, which raises the driver D to the head of theframe,` when ,the trip-lever Q strikes against the stop S, tripsthehookK, and unhooks it from the hoop l'zI. The driver then Vfalls uponthe hay or cotton, and drives it down upon the follower U, which isgradually descendin g at the same time by the reverse movements of thenut. The forked trip-lever R then strikes the other stop S,and againengages the hook K with the hoop IzI,which causes the cord F attached toit to be wound upon it, and at the same time filling in hay or cotton tothe box, which he constantly keeps filled. As the driver rises and thefollower descends, the trip-lever again comes in contact with the stopS, trips the hook, and disengages the hoop to which the cord isattached,.which then slips around upon the wheel, allowingthe driver toagain fall upon the loose hay or cotton as before; and in thismanner'the operation is con' tinued until the follower is down and asufficient quautity of hay or cotton is driven into the box to form thebale. The driver D is then made fast in the posts A of the frame in themanner hereinafter described, and becomes the head-block against whichthe bale is to be are then opened and the bal'e tied.

pressed. The motion of the nut M is then reversed by changing thedirection of the horse, which causes the screw N to rise with thefollower and hay or cotton thereon, which it presses against the driverD in its permanent position until sufficiently pressed. The doors rlhemotions of the nut is again reversed by again changing thel direction ofthe horse, and after having performed about two' revolutions the hook isagain thrown out of its mortise, and engages with the hoop, whichunfastcns the driver from the posts and raises it to the tops thereof.

rIhe fastening and unfastening the driver from the posts is effected inthe following manner: The driverD is composed of two parallel verticaltimbers, D', which slide between the posts in the manner of saw-gate ofasaw-mill. These timbers are united by horizontal parallelcross-timbers. The'middle timber, cl d, is divided diagonally into twowedged-shaped timbers, which slide horizontally in mortiscs in thebefore-mentioned vertical timbers D', and enter corresponding mortisesin the posts A, the large ends entering the mortises. These slidingwedged-shaped timbers d cl are united by a toggle-joint, E, one end ofthe joints being attached to vthe large end of each piece.

The rope Fis attached to the middle of the toggle E. When the driver islet down to its position to act as head-block,the joint is straightcnedor brought nearly in a right line, which drives the two parts of thedivided timber d d in contrary direction, the large end of one pieceentering one of the mortises in the posts, and the other entering themortise in its corresponding opposite posts, which thus secures or locksthe driver to the posts and forms the head-block. When the joint isagain bent by drawing the cord, the two aforesaid wedgedshaped timbers dd are drawn from the mortises inthe posts and the driver becomesdisengaged therefrom.

Vhat I claim as my invention, and which I desire to secure by LettersPatent, is-

Filling the box with the substance to be pressed into bale by means of adriver raised by machinery and made to descend upon the substance in thebox successively by gravity as the follower descends, whether effectedin the manner above described or in any other mode analogous thereto.
